FLUE-IE'IPE SUPPORT AND INSULATQR.

Application filed December 10, 1924.

portand insulator for fine pipes for gas heaters and the like whichoperates to center, effectively support, and maintain a due pipe inproper spaced relation to the infiannnable parts of the ceiling and roofof a building whereby a passage around the flue pipe provided throughwhich air is free to circulate. thus reducing to a minin'ium thepossibility of fire. It is also a purpose of my invention to provide afine pipe support and insulator which in addition to possessing thedesirable qualities of simplicity,durability and inenpensiveness, iscapable of application to the two ends of a fine pipe, and in practicethe device at the lower end of the pipe supports thelatter, while thedevice at the upper end of the pipe. is inverted to receive, center andhold the pipe in spaced relation to the inflammable parts of the roofthrough which it extends.

I will describe only one form of pipe support and insulator embodying myinvention and will then point out the novel features in claims.

In the accompanying drawings,

Figure 1 is a view showing in vertical section one form of flue pipesupport and insulator embodying my invention in applied position withrespect to a fine pipe;

Figure 2 is an enlarged transverse sectional view taken on the line 2-2of Figure 1;

Figure 3 is a perspective view of the device shown in the precedingviews.

Referring specifically to the drawings, in which similar referencecharacters refer to similar parts, my invention, in its presentembodiment, is shown in Figures 1 and 2 as comprising a body 15 formedof sheet unetal or other suitable material which, in

the present instance, is circular and hollow, one end of the body beingformed with a flange inturned to provide an annular collar 16. Thecollar 16 is formed at circumferentially spaced intervals with openings17,

and its inner peripheral. edge is bent inwar-(1y and downwardly to forman ai'inular lip 18. liitl'iin the body are arranged a piurality ofretaining members 19. lin the present instance I have shown threeretaining members spaced 120 dliil'b and eacl member con'iprising a leafspring secured at its ends by rivets or othe" suitable fasteir ingmembers 20, while its i tion is bowed inwardly so as to engage theperiphu'y or a flue pipe inserted therein.

As shown in Figure 3, the opposite end of the body 15 is split atintervals as indicated at 21, to provide tongues 22 which can be bentoutwardly at right angles to the periphery of the body to provideattaching means tor sci'uring the body to a support. In practice, thebody 15 is covered with a jacket 23 of asbestos or other suitablematerial for the purpose of preventing the radiation or heat through thebody to the parts of a building with which the device contacts when inapplied position.

Referring now to Figure 1, T have here shown a conventional form oi fluepipe in cluding a lower section 24 and an upper section 25, the formerbeing supported in upright position by one of the combined supports andinsulators embodying my invention. In the applied position of the deviceit is inverted so that the collar 16 is disposed at the lower end of thebody 15 to engage the lower endof the pipe 2% and support the latter.The lip 18 is disposed inwardly of the pipe end, as illustrated, andthus serves to properly center the pipe within the body. However, theretaining members 19 co-operate with the lip 18 in confining the pipeagainst lateral movement within the body and to thus maintain the pipein properly spaced relation to the body so as to provide between the twoa circular passage 26. through which air is free to circulate. Theperforations 17 in the collar 16 allow the passage of air upwardly intothe chamber 26. The body 15 is securely held in the ceiling of thebuilding by driving through the angularly disposed tongues 22 nails orother suitable fastening members, the latter puncturing adjacent partsor the ceiling structure 1. ntermediate porwhereby the device as a unitis firmly held within the opening of the ceiling.

To maintain the upper pipe section 25 in proper spaced relation to theroof of the building, another combined support and insulator is providedwhich in applied posillU upwardly therethrough, the air passing out ofthe chamber througl'i the perforations 17.

With the two devices applied as just described, it will be manifest thatthey co-oper ate in firmly supporting the pipe sections in uprightposition and in maintaining the same in spaced relation with respect tothe adjacent inflammable parts of the ceiling and roof, so as'to allowthe free circulation of air therebetween and thus reduce to a minimumthe possibility of fire. Whatheat is conducted from the pipe through thebody of the device is prevented from being transmitted to the adjacentparts ct the building structure'by virtue of the jacket insulatingmaterial 23.

Although I have herein show and described only one form of flue pipesupport and insulator embodying my invention, it is to be understoodthat various changes and modifications may be made Without departingfrom the spirit of my invention and the spirit and scope of the appendedclaims.

I claim as my invention:

1. A support for flue pipes comprising a hollow body having one end bentover to form a collar and inwardly to provide an annular lip on theinner periphery of the collar, said collar formed with circumferentiallyspaced openings, resilient members for movably holding the pipe in saidbody, a heat insulating jacket enclosing said body and the opposite endof the body being split at intervals to form bendable tongues.

2. A support for flue pipes comprising a hollow body, a collar formed onone end of the body, an annular lip on the inner periphery of thecollar, and retaining members in the body, each comprising a resilientelement adapted for frictionally engaging the pipe and co-operating withthe lip to center the pipe in the body.
